CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a Continuation Application of prior U.S. patent application Ser. No. 15/855,569 filed Dec. 27, 2017, which claims priority under 35 U.S.C. § 119 to Korean Application No. 10-2016-0180503 filed on Dec. 27, 2016, whose entire disclosures are hereby incorporated by reference.

BACKGROUND 1. Field

A vacuum cooking appliance is disclosed herein.

2. Background

In addition to cooking methods such as, for example, oven cooking, grilling, and steaming, using an open-type cooking appliance or a closed-type cooking appliance, new cooking methods have been developed. One cooking method is sous-vide cooking. Sous-vide cooking is a cooking method that may preserve nutrients, texture, and taste, by cooking under a vacuum. Sous-vide cooking was first designed in 1799 by Benjamin Thompson, Count Rumford, with later contributions by American and French engineers in the 1960s as a food preservation method, and was developed by Bruno Goussault after sous-vide cooking was used to cook foie gras by George Pralus in 1974. French “sous-vide” refers to a low-temperature vacuum cooking method, also known as “under vacuum” in English. Since 1970, sous-vide cooking has been used in some luxury restaurants in Europe, and around the world in restaurants and hotels, for example.

Sous-vide cooking is a method in which food contained in a sealed plastic bag is heated for a long time in low-temperature water that may be maintained in a range of about 50° C. to 60° C. Sous-vide cooking may maintain an original taste of a material to preserve all texture, flavor, and nutrients at its peak, and for example, keep a peak texture of food. Sous-vide cooking may be capable of preventing meat from being too tough due to protein modification when cooked at a high temperature to maintain softness and moistness of the meat, and may evenly heat an inside and an outside of the food cooked via sous-vide cooking.

In sous-vide cooking, it may be very important to constantly maintain a temperature of water or liquid that cooks the food for a long time, and to firmly seal the food to be cooked by packing the food in a vacuum state. However, as sous-vide cooking may take a long time for cooking food, for example, from 4 hours to 48 hours, and adjustments of a cooking temperature and a cooking time may be very difficult, a separate dedicated cooking appliance may be required for effective sous-vide cooking. In order to package food to be cooked in a vacuum state, a separate vacuum package machine may be required. That is, for effective sous-vide cooking, a separate dedicated cooking appliance for sous-vide cooking may be required, and it may be inconvenient to provide a separate vacuum package machine for packing food to be cooked in a vacuum state.

Further, when the separate dedicated cooking appliance for sous-vide cooking and the separate vacuum package machine are provided, it may be difficult to provide sufficient space for installing the separate dedicated cooking appliance and the separate vacuum package machine. When the separate dedicated cooking appliance and the separate vacuum package machine are respectively installed at positions separated from each other, it may be inconvenient to perform the vacuum packing, the sous-vide cooking, and cooking of other materials at different positions.

DETAILED DESCRIPTION

Referring to FIG. 1 to FIG. 4, a vacuum cooking appliance 100 according to an embodiment may include a housing 110, a second container 120, a heating part or heater 130, a cover mounting part or cover mount 140, a cover 145, and a vacuum packing module 150. The housing 110 may be in a form of a quadrangular frame in which a mounting hole 110 a may be provided. Bent extensions 112 and 113 may be provided at an upper end edge of the housing 110 and may be formed to protrude outward from the housing 110 to form a coupling surface with the cover mount 140 at an upper end of the housing 110.

The bent extensions 112 and 113 may be formed to include a horizontally bent extension 112 bent outward to extend from the upper end of the housing 110, and a vertically bent extension 113 bent downward to extend from the horizontally bent extension 112. The bent extensions 112 and 113 may be formed across an entire upper end edge region or edge of the housing 110, which may include a container mount 111 as well as a vacuum packing module mount 115.

The container mount 111 and the vacuum packing module mount 115 may be provided at the housing 110. The container mount 111 may be provided at the housing 110 to allow a first container 114 and the second container 120 to be installed, and may correspond to a part or portion located at a rear side of the housing 110 when the housing 110 is divided along a frontward and rearward or first direction. The container mount 111 may be configured to include the mounting hole 110 a and a frame enclosing the mounting hole 110 a at an outer side thereof.

The first container 114 may be installed at or in the container mount 111. The first container 114 may be in a form of a box made of, for example, a metal material, in which an accommodating space may be formed and having an open upper portion. The first container 114 may correspond to a part or portion provided at the housing 110 to allow the second container 120 to be accommodated in the first container 114. The first container 114 may be in a form of a box having a hexahedral shape, in which a width may increase in an upward direction and an accommodating space may be formed inside the first container 114, and having an open upper surface.

The vacuum packing module mount 115 may correspond to a part or portion located in front of the housing 110 when the housing 110 is divided along the frontward and rearward or first direction. The vacuum packing module mount 115 may be formed to include the mounting hole 110 a and the frame enclosing the mounting hole 110 a at the outer side thereof, and to be connected to the container mount 111 to make a shape of a quadrangular frame. The vacuum packing module mount 115 may correspond to a part or portion provided at the housing 110 to allow the vacuum packing module 150 to be mounted on the vacuum packing module mount 115.

The vacuum packing module mount 115 may be formed in a shape of a polygonal frame that protrudes forward from the container mount 111, and a bottom surface of the vacuum packing module mount 115 may be formed to be located above a bottom surface of the first container 114. An electronic component space a may be formed below the vacuum packing module mount 115.

The above-described housing 110 including the container mount 111 and the vacuum packing module mount 115 may be formed to integrally connect the container mount 111 and the vacuum packing module mount 115. The second container 120 and the heating part 130 may be installed at the container mount 111, and the vacuum packing module 150 may be mounted on or at the vacuum packing module mount 115, and thus the vacuum cooking appliance 100 may be provided such that a configuration for cooking food or other items (hereinafter “food”) at a low temperature and a configuration for vacuum packing the food may be integrally provided in a single appliance.

The second container 120 may be provided to accommodate thereinside a liquid, such as water, and may be provided to be withdrawn from the first container 114. As shown in FIG. 3 to FIG. 6, the second container 120 may be configured to include a container main body 121, a container cover 123, and a handle 125.

The container main body 121 may be in a form of a box, and may have an accommodating space formed inside the container main body 121 and an open upper portion. The second container 120 may have a form similar to that of the first container 114, but it may be a box having a hexahedral shape, which has a height less than a height of the first container 114. The container main body 121 may be formed of, for example, a metal material with high thermal conductivity.

The container cover 123 may be provided in a form of a quadrangular-shaped plate capable of covering the open upper portion of the container main body 121, and may be seated or placed on the second container 120 to cover an open upper portion thereof. The container cover 123 may block vapor, which may be generated when water or liquid inside the second container 120 is heated, from leaking out of the second container 120, block heat transmitted to the cover 145 to prevent the cover 145 from being overheated, and prevent the water or liquid from overflowing when the second container 120 is moved. A gasket g may be installed at an interface between the container cover 123 and the container main body 121 to improve a sealing force therebetween.

The handle 125 may be provided at a lateral portion of the container main body 121, and may be installed to be capable of vertically extending from and retracting into the lateral portion thereof. A flange may be formed to laterally protrude from an upper end portion or end of the container main body 121, and the handle 125 may be formed in a form of a ring to be vertically slidably coupled to the flange.

The handle 125 may be slidably coupled to the lateral portion of the container main body 121 so as to be changed to a hidden position (see FIG. 5) located inside the first container 114 to prevent the handle 125 from protruding out of the housing 110, and to a protruding position (see FIG. 6) at which the handle 125 protrudes out from the first container 114. A protruding degree of the handle 125 at the protruding position may be such that a user may be able to grip the handle 125 outside the first container 114 to lift the second container 120 mounted inside the first container 114.

When the handle 125 is installed at the container main body 121 instead of being installed at the container cover 123, there may not be a need to add a component, such as a buckle, to fix the container cover 123 to the container main body 121, so that a configuration of the second container 120 may be simplified. As the handle 125 is configured to vertically protrude and retract, a volume occupied by the handle 125 in the second container 120 may be reduced, and thus, a volume of the first container 114 required for being accommodated in the second container 120 may be reduced so that an entire size of the housing 110, the first container 114, and the cooking appliance including the housing 110 and the first container 114 may be reduced.

Referring to FIG. 1 to FIG. 4, the heating part 130 may be configured to be installed at the housing 110 to heat the liquid contained inside the second container 120. The heating part 130 may be provided as a low-temperature heater configured to heat the liquid contained inside the first container 114, that is, contained inside the second container 120 at a temperature of 100° C. or less.

The heating part 130 may include a plate-shaped electric heater 131 installed at a lower portion of the first container 114 so as to be located on a bottom surface of the second container 120 mounted inside the first container 114. The electric heater 131 may be in contact with a bottom surface of the container main body 121 and may heat water or liquid contained inside the second container 120. The heating part 130 may be implemented in various modifications in which the heating part 130 may be installed to be in contact with another portion in addition to the bottom surface of the container main body 121, may be provided in a form of a coil-shaped heater, and may include a heating device configured to heat the second container 120 by an induction heating method rather than the electric heater 131.

The heating part 130 may further include a temperature measurement part or sensor 133 and a temperature control part or controller 135. The temperature sensor 133 may sense a temperature of the second container 120 heated by the electric heater 131 or a temperature of the water or liquid accommodated inside the second container 120. The temperature controller 135 may control an operation of the electric heater 131 to maintain the temperature of the second container 120 or the temperature of the water or liquid accommodated inside the second container 120 at a predetermined temperature. The temperature sensor 133 may include a thermistor, and the temperature controller 135 may include a thermostat.

The cover mount 140 may be in a form of a quadrangular frame with a shape corresponding to a shape of an upper end edge of the housing 110 and may be installed at an upper portion thereof. An opening hole 141 may be formed to pass through the cover mount 140 and may be configured to open upward the second container 120, which may be accommodated in the first container 114, and the vacuum packing module 150.

The cover mount 140 may be coupled to the bent extensions 112 and 113, which may be formed at the upper end edge of the housing 110, and installed at the upper portion of the housing 110. The cover mount 140 may correspond to a coupling medium configured to couple the cover 145 to the upper portion of the housing 110.

The cover 145 may be installed at the cover mount 140 to open and close the opening hole 141. The cover 145 may include a cover glass 146 and a cover plate 147. The cover glass 146 may be in a form of a quadrangular-shaped plate capable of covering the opening hole 141, and may be formed of, for example, a transparent or semitransparent glass or plastic material, for example. The cover plate 147 may be in a form of a quadrangular-shaped plate corresponding to the shape of the cover glass 146, and may be coupled to a lower portion of the cover glass 146 to support the cover glass 146. A viewing window w may be formed to vertically pass through an inside of the cover plate 147, and an internal state of the vacuum cooking appliance 100 covered by the cover 145 may be viewed from an outside through such a viewing window w.

One or a first end portion or end of the cover 145 may be pivotably coupled to the cover mount 140, and the cover 145 may be pivoted based on the one end portion pivotably coupled to the cover mount 140 to open and close the opening hole 141. For example, the one end portion of the cover 145 may be vertically pivotably coupled to a hinge 149 installed at the cover mount 140, and the cover 145 may be vertically pivoted based on the one end portion to open and close the opening hole 141.

A hook h may be provided to protrude from another or second end portion or end of the cover 145 opposite to the one end portion of the cover 145 to fix the other end portion of the cover 145 to the housing 110 or the cover mount 140. A latch mechanism or latch r may be provided at a portion of the housing 110 or the cover mount 140, which corresponds to the hook h, and may be detachably coupled to the hook h. A mechanism that allows the hook h and the latch mechanism r to be sequentially engaged with and disengaged from each other by a pressing operation to the other end portion of the cover 145 at which the hook h is installed, may be applied as the latch mechanism r. Consequently, the cover 145 may be pivoted based on the one end portion thereof pivotably coupled to the hinge 149 to open and close the opening hole 141, while the other end portion of the cover 145 may be fixed to the housing 110 or the mount 140 as needed through coupling of the hook h and the latch mechanism r such that a closed state of the cover 145 may be stably maintained.

By opening and closing operations performed by the cover 145, the second cover 120 and the vacuum packing module 150, which may be mounted on the housing 110, may be exposed to the outside or may be covered with the cover 145. A gasket g may be installed at an interface between the cover 145 and the cover mount 140 to improve a sealing force therebetween.

The cover 145 may be divided into a pressurizing region 145 a and a covering region 145 b. The pressurizing region 145 a may be a region facing the vacuum packing module 150 when the cover 145 closes the opening hole 141, and may correspond to a region at which the cover 145 covers and pressurizes the vacuum packing module 150 from above. The covering region 145 b may be a region facing the first container 114 and the second container 120 when the cover 145 closes the opening hole 141, and may correspond to a region at which the cover 145 covers an open upper portion of the first container 114.

Referring to FIG. 2 to FIG. 4, the vacuum packing module 150 may be installed at or in the vacuum packing module mount 115. The vacuum packing module 150 may be configured to include a vacuum pressure generator 151 configured to generate a vacuum pressure that forms a vacuum inside a food packing container or bag p, and a sealer 155 configured to generate heat to seal an open inlet side or opening of the food packing container p. The food packing container p may be a packing material made of, for example, a vinyl material, in which a space for accommodating food is formed and an open inlet or opening is formed.

The vacuum pressure generator 151 may form a vacuum inside the food packing container p, and as shown in FIG. 7 to FIG. 10, the vacuum pressure generator 151 may include a vacuum panel 152 and a vacuum pump 153. The vacuum panel 152 may provide a frame at which various components of the vacuum packing module 150 may be installed, and a supporting surface 152 a configured to support some of the food packing container p from below. The vacuum panel 152 may be in a form of a quadrangular-shaped plate capable of covering the penetrating inside of the vacuum packing module mount 115, and an air inlet 152 b and a packing bag insertion part or portion 152 c may be formed at the vacuum panel 152.

The air inlet 152 b may be formed to pass through the vacuum panel 152. A protrusion that protrudes downward to enclose the air inlet 152 b may be formed on a lower surface of the vacuum panel 152, at which the air inlet 152 b is formed, and the protrusion may be a portion to which a connecting hose 154 configured to connect the vacuum pump 153 to the air inlet 152 b may be coupled.

The packing bag insertion part 152 c may be configured as a concave surface into which the open inlet side of the food packing container p is inserted. The packing bag insertion part 152 c may be concave downward from the supporting surface 152 a. Consequently, an insertion space enclosed by a side surface, which connects between the packing bag insertion part 152 c and the supporting surface 152 a, may be formed and the open inlet side of the food packing container p may be inserted into the insertion space. The air inlet 152 b may be formed to pass through the packing bag insertion part 152 c and may be located inside the insertion space.

The vacuum pump 153 may be provided to generate a vacuum pressure acting on the air inlet 152 b and may be installed and positioned below the vacuum panel 152. If the vacuum pump 153 is accommodated inside a pump case 153 a provided and coupled to a lower portion of the vacuum panel 152, the pump case 153 a may be coupled to the lower portion of the vacuum panel 152 so that the vacuum pump 153 may be installed. The vacuum pump 153 may be connected to the air inlet 152 b through the connecting hose 154, and the vacuum pressure generated by an operation of the vacuum pump 153 may act through the air inlet 152 b connected to the connecting hose 154.

A first seal d1 may be installed at the vacuum panel 152 at which the vacuum pump 153 is installed to enclose a periphery of the packing bag insertion part 152 c. The first seal d1 may be formed in a closed curve shape enclosing the packing bag insertion part 152 c and the air inlet 152 b formed at the packing bag insertion part 152 c. A second seal d2, which may be in a shape corresponding to a shape of the first seal d1, may be installed at the pressurizing region 145 a of the cover 145. The second seal d2 may engage with the first seal d1 when the opening hole 141 is closed by the cover 145 to seal the insertion space inside the packing bag insertion part 152 c.

At least one of the first seal d1 or the second seal d2 may be made of, for example, a buffer material, and the insertion space inside the packing bag insertion part 152 c may be sealed by engagement between the first seal d1 and the second seal d2. Accordingly, the vacuum pressure acting through the air inlet 152 b may fully act on the inlet side of the food packing container p accommodated in the insertion space.

The sealer 155 may generate heat to seal the open inlet side of the food packing container p and may be configured to include a hot wire configured to generate heat using a current. The hot wire of the sealer 155 may be in a straight line in parallel to the packing bag insertion part 152 c provided at the vacuum panel 152, may have a length corresponding to a length of the packing bag insertion part 152 c, and may be spaced apart by a predetermined interval from the packing bag insertion part 152 c in the frontward and rearward or first direction. The hot wire may be installed at the supporting surface 152 a of the vacuum panel 152 and may be exposed above the vacuum panel 152. The hot wire of the sealer 155 may be provided between the packing bag insertion part 152 c of the vacuum pressure generator 151 and the first container 114.

A pressurizing member 148 may be provided at the pressurizing region 145 a of the cover 145. The pressurizing member 148 may be in contact with the hot wire of the sealer 155 when the cover 145 closes the opening hole 141, and may be in a form of a pad made of, for example, a buffer material, which may have a width that is greater than a width of the hot wire of the sealer 155. The pressurizing member 148 may pressurize the inlet side of the food packing container p in a direction immediately close to the hot wire of the sealer 155 such that the sealing of the food packing container p by the hot wire may be more effectively performed.

When the cover 145 closes the opening hole 141, the pressurizing region 145 a of the cover 145, at which the first seal d1 and the pressurizing member 148 may be installed, may cover an upper portion of the vacuum packing module 150, and may cover the vacuum pressure generator 151 and the sealer 155 of the vacuum packing module 150 to allow the first seal d1 to be engaged with the second seal d2 and to allow the pressurizing member 148 to be in contact with the hot wire of the sealer 155.

When the pressurizing region 145 a covers the vacuum pressure generator 151 and the sealer 155 of the vacuum packing module 150, the inlet side of the food packing container p may be fixed in a sealed space formed by the first seal d1 and the second seal d2 and may be pressed to the hot wire of the sealer 155 by the pressurizing member 148 to be in close contact with the hot wire of the sealer 155.

Referring to FIG. 9, the container cover 123 of the second container 120 mounted on the first container 114 may be provided such that a seating surface or seat 123 a may be formed on an upper surface of the container cover 123. The seating surface 123 a may be recessed downward from an edge of the container cover 123 to form a plane located below a plane formed by the supporting surface 152 a of the vacuum panel 152 and a plane formed by the packing bag insertion part 152 c.

The seating surface 123 a may form a plane on which a remaining portion of the food packing container p, for example, a portion in which a cooking material is accommodated may be seated. The seating surface 123 a may form a plane located below the plane formed by the supporting surface 152 a of the vacuum panel 152 and the plane formed by the packing bag insertion part 152 c, and spaced apart downward by a predetermined interval from a plane formed by the covering region 145 b of the cover 145 when closing the opening hole 141. Consequently, a packing bag accommodating space s in which the food packing container p may be accommodated may be formed between the covering region 145 b of the cover 145 when closing the opening hole 141 and the seating surface 123 a.

Referring to FIG. 1 to FIG. 4, the vacuum cooking appliance 100 may further include an outer case 160 and a control panel 170. The outer case 160 may be provided to form an exterior appearance of the vacuum cooking appliance 100 in addition to the cover mount 140 and the cover 145. The outer case 160 may be coupled outside the housing 110 to accommodate the housing 110 therein, and an accommodating space that accommodates the housing 110 and the electronic component space a may be formed inside the outer case 160.

The outer case 160 may be in a form of a box having a hexahedral shape, in which the accommodating space may be formed and having an open upper surface. An upper end edge of the outer case 160 may be coupled to the bent extensions 112 and 113 of the housing 110 to be engaged with the housing 110, or may be coupled to a lower end edge of the cover mount 140 to be engaged with the housing 110 through coupling to the cover mount 140.

The vacuum packing module mount 115 of the housing 110 may be formed and provided at a position that protrudes forward from the container mount 111 and the first container 114, and may be formed to have a lower surface of the vacuum packing module mount 115 above a lower surface of the first container 114. The electronic component space a may be formed below the vacuum packing module mount 115. The electronic component space a may be a region located in front of the container mount 111 and the first container 114, and may be configured to include a region located below the vacuum packing module 150 mounted on the vacuum packing module mount 115.

The outer case 160 may form an accommodating space for the housing 110, the first container 114, and the electronic component space a, and an outer boundary surface of the electronic component space a may be defined by the outer case 160. That is, the electronic component space a may be configured with a space with which an upper boundary surface is defined by the vacuum packing module 150, one lateral boundary surface is defined by the first container 114, and a lower boundary surface and remaining three lateral boundary surfaces may be defined by the outer case 160.

The first container 114 may have a shape with a length that is greater than a vertical length of the second container 120 so as to accommodate the second container 120, so that each of the vacuum packing module mount 115 and the vacuum packing module 150 may not need to be installed to have a vertical length the same as that of the first container 114. Therefore, an available space in which a component directly related to the vacuum packing module 150 is not provided may be secured in a lower region of a portion at which the vacuum packing module mount 115 and the vacuum packing module 150 are provided, and thus, a space secured at a front side position inside the outer case 160 may correspond to the electronic component space a.

The electronic component space a may accommodate an electronic component installed in connection with an operation of the heating part 130, an electronic component installed in connection with an operation of the vacuum packing module 150, an electronic component installed in connection with an operation of the control panel 170, electronic components related to a connection of the above-described components, and electronic components related to a supply of electricity to the above-described components. Also, a component, such as a cooling fan, may be installed in the electronic component space a to cool the above-described electronic components installed in the electronic component space a.

The control panel 170 may be provided on a front surface of the vacuum cooking appliance 100. The control panel 170 may be in a hexahedral shape having a predetermined internal space, and an input unit or input, to which a user may input a manipulation signal to operate the heating part 130 and the vacuum packing module 150, may be provided on a front surface of the control panel 170.

A plurality of manipulation switches may be provided at the input, and the user may directly input the manipulation signal through the plurality of manipulation switches. A display may be provided at the control panel 170 to provide operation information of the vacuum cooking appliance 100, and the user may determine various information regarding the vacuum cooking appliance 100 through the display.

The control panel 170 may be installed at the outer case 160 and may be installed on the front surface of the outer case 160 adjacent to the electronic component space a. The control panel 170 may be installed at the front surface adjacent to the electronic component space a, so that the various electronic components installed in the electronic component space a and the control panel 170 may be efficiently connected, and a connection line for such a connection may be configured more simply.

Referring to FIG. 1 to FIG. 4, the vacuum cooking appliance 100 may be provided such that a configuration for vacuum packing the food packing container p and a configuration for heating the vacuum packaged food may be included together in a single appliance having an exterior shape defined by the cover 145, the cover mount 140, and the outer case 160.

The vacuum cooking appliance 100 as described above may be used in the following manner. First, as shown in FIG. 2 and FIG. 4, the cover 145 may be pivoted to open the inside of the vacuum cooking appliance 100, and then water or liquid required for cooking may be filled inside the second container 120. The water or liquid may be filled inside the second container 120 in a state in which the second container 120 is taken out from the first container 114 or in a state in which the second container 120 is mounted on the first container 114. After the water or liquid required for cooking is filled inside the second container 120, the container cover 123 may be placed on the upper portion of the container main body 121.

When food has been vacuum packed, it may be cooked by being put into the second container 120 before covering the container cover 123, but, when a vacuum packing is required for the food, vacuum packing may be performed using the vacuum packing module 150. The vacuum packing operation using the vacuum packing module 150 may be performed as follows.

First, after the food is placed inside the food packing container p, the food packing container p may be provided to allow the open inlet side of the food packing container p to be located at the vacuum packing module 150, so that the food packing container p may be prepared for a vacuum packing.

An end portion or end of the open inlet side of the food packing container p may be inserted into the packing bag insertion part 152 c, and a lateral surface of the inlet side of the food packing container p, which may be located outside the packing bag insertion part 152 c, may be provided above the supporting surface 152 a of the vacuum panel 152 and the hot wire of the sealer 155. Further, the remaining portion of the food packing container p may be placed and located on the second container 120, that is, the remaining portion may be placed and seated on the seating surface 123 a formed at an upper portion of the container cover 123.

Accordingly, the food packing container p to be vacuum packed may be first placed on the seating surface 123 a formed on the upper portion of the container cover 123, and may be provided at a convenient position for a vacuum packing in a stable state. Then the end portion of the open inlet side of the food packing container p may be inserted into the packing bag insertion part 152 c, so that the packing bag insertion part 152 c may be prepared. A seated portion of the seating surface 123 a of the food packing container p may be stably accommodated in the packing bag accommodating space s inside the first container 114 in a form in which a lower portion of the food packing container p is supported by the seating surface 123 a and a lateral portion thereof is enclosed by the first container 114.

When the food packing container p is vacuum packed, a supporting surface may be insufficient to seat another portion located outside the vacuum packing machine except for a portion located inside the vacuum packing machine, and thus, it may be inconvenient as the user may need to hold the food packing container p to prevent contents inside the food packing container p from leaking out until the operation of the vacuum packing is completed. For example, as the user may need to use the vacuum packing machine with one hand, the food packing container p may be held by one hand, and thus, operation of the vacuum packing may be performed in an unstable state.

On the other hand, in the vacuum cooking appliance 100, a support structure may be provided to be able to seat most of the food packing container p located outside the vacuum packing module 150 on the seating surface 123 a formed at the upper portion of the second container 120, as described above. That is, the food packing container p to be vacuum packed may first be placed on the seating surface 123 a formed at the upper portion of the container cover 123, and may be located at a convenient position for vacuum packing in a stable state, and then the end portion of the open inlet side of the food packing container p may be inserted into the packing bag insertion part 152 c, so that the packing bag insertion part 152 c may be prepared for vacuum packing.

The seating surface 123 a on which the food packing container p is seated may form a plane located below the plane formed by the packing bag insertion part 152 c into which the inlet side of the food packing container p is inserted, so that the food packing container p may be seated to locate the open inlet side thereof at a position above the remaining portion of the food packing container p which is seated on the second container 120. Consequently, even in a state in which the user does not directly hold the food packing container p, the food packing container p may remain in a stable state so as to prevent the food inside the food packing container p from leaking out and may be prepared in the vacuum cooking appliance 100.

As described above, when preparation of the food packing container p for the vacuum packing is completed, the cover 145 may be closed to press the food packing container p between the vacuum panel 152 and the cover 145. Due to the shape of the seating surface 123 a formed to be recessed downward, the packing bag accommodating space s may be formed between the covering region 145 b of the cover 145 and the seating surface 123 a of the container cover 123, so that, even when the cover 145 is closed, the portion seated on the seating surface 123 a may be stably accommodated in the packing bag accommodating space s without being pressed by the cover 145.

When the cover 145 is closed and then the vacuum pump 153 is operated, a vacuum pressure may act on the inside of the packing bag insertion part 152 c, and the inside of the food packing container p may be changed to a vacuum state by the vacuum pressure. Then, when the sealer 155 is operated to perform a sealing operation in a state in which the operation of the vacuum packing for the food packing container p is completed, the food packing container p may be sealed in a vacuum state, and thus, the operation of the vacuum packing for the food packing container p may be completed.

The hot wire of the sealer 155 that performs the sealing operation on the food packing container p may be provided and located between the packing bag insertion part 152 c and the first container 114, that is, between the packing bag insertion part 152 c and the seating surface 123 a. A configuration for sealing the food packing container p may be provided between a position at which a configuration for vacuum suctioning the inside of the food packing container p and a position at which the food packing container p is seated and supported.

Accordingly, when the food packing container p to be vacuum packaged is stably seated on the seating surface 123 a formed at the upper portion of the container cover 123, the vacuum operation by the vacuum pressure generator 151 may be stably performed as well as the sealing operation by the sealer 155 may also be effectively performed in the same state.

The operation of the vacuum cooking appliance 100 as described above may correspond to a synergistic effect achieved by combining the configuration for vacuum packing the food packing container p and the configuration for heating a vacuum packaged cooking material into a single appliance. That is, the vacuum packing module 150, which is the configuration for vacuum packing the food packing container p, and the second container 120, which is the configuration for heating the vacuum packaged cooking material, may be respectively provided at adjacent positions and may be a single appliance, and thus, a structure for stably supporting the food packing container p may be provided by the second container 120, so that the operation of the vacuum packing may be conveniently stably performed while the food packing container p is maintained in a stable state so as to prevent the food from leaking out even if the user does not directly hold the food packing container p.

After the operation of the vacuum packing by the vacuum packing module 150 is completed, the container cover 123 may be opened and the vacuum packaged food may be put into the second container 120, when the cover 145 is open. Then, after the container cover 123 and the cover 145 are closed, the heating part 130 may be operated to heat the vacuum packaged food so that low-temperature cooking for food is performed. The container cover 123 covering the container main body 121 may block vapor generated when the water inside the second container 120 is heated, from leaking out of the second container 120, and may block heat from being transmitted to the cover 145, thereby serving to prevent overheating of the cover 145.

The operation of the heating part 130 may be initiated when the user manipulates the input of the control panel 170 to input a heating temperature and an operation signal, and thus, the low-temperature cooking for the food may be performed such that the electric heater 131 of the heating part 130 heats the water inside the second container 120 according to the input heating temperature.

According to the vacuum cooking appliance 100, electric and electronic components, such as, for example, electronic components installed in connection with the operation of the heating part 130, electronic components installed in connection with the operation of the vacuum packing module 150, electronic components installed in connection with the operation of the control panel 170, electronic components related to a connection of the above-described electronic components, and electronic components in connection with a supply of electricity to the above-described electronic components, may be installed and accommodated in the electronic component space a inside the outer casing 160.

The electronic component space a is configured with a space with which the upper boundary surface may be defined by the vacuum packing module 150, the one lateral boundary surface may be defined by the first container 114, and the lower boundary surface and the remaining three lateral boundary surfaces may be defined by the outer case 160. The electronic component space a may be a space that may be secured due to the configuration for vacuum packing the food packing container p and the configuration for heating the vacuum packaged cooking material being integrally included in a single appliance.

That is, the electronic component space a may be a space formed by adjacently mounting the vacuum packing module 150 having a relatively short vertical length in front of the first container 114 provided to have a relatively long vertical length, so that the electronic component space a may be a space that may be specifically secured only inside the vacuum cooking appliance 100.

When an appliance configured to vacuum package the food packing container p and an appliance configured to heat the vacuum packaged cooking material are separately configured, a space required for electric and electronic components may need to be secured in each appliance. When considering an entire exterior appearance of each appliance, in order to secure the space required for installing the electric and electronic components in each appliance, a size of each appliance may become larger than necessary.

On the other hand, in the vacuum cooking appliance 100, installation of electric and electronic components required for the configuration for vacuum packing and the configuration for heating the vacuum-packed cooking material may be in the electronic component space a that is a single integrated space, and the electronic component space a may be a space that may be naturally secured as the configurations for implementing different functions are installed in a single appliance. Thus, the vacuum cooking appliance 100 may have a compact size and an aesthetically simple beauty when compared with a case in which these configurations are respectively configured with separate appliances.

The vacuum cooking appliance 100 as described above may perform low-temperature cooking, such as sous-vide cooking. The operation of the vacuum packing required for the operation of the low-temperature cooking with a single appliance without separately providing separate dedicated cooking appliances for the sous-vide cooking and the separate vacuum package machine, so that a cooking appliance, which may be economical, efficient, and improved in usability, may be provided.

In addition, as the vacuum cooking appliance 100 may perform the vacuum packing while maintaining the food packing container p in a stable state so as to prevent the food from leaking out, the operation of the vacuum packing may be more conveniently and stably performed. Further, the vacuum cooking appliance 100 may allow configurations for implementing different functions, such as the configuration for vacuum packing the food packing container p and the configuration for heating the vacuum packed cooking material, to be integrally included in a single appliance, as well as may be manufactured in an appliance having a compact size and a simple exterior appearance, so that an installation space may be easily secured.
